The length and breadth of a rectangle are (3x-2) and (2x+5) respectively. Find the perimeter and area of the rectangle?​

G(a) = a^2 - 5a + 5

Equation of the tangent line passing through (0,5): y = -5x + 5

Equation of the tangent line passing through (6,11): y = 7x - 31

To find G(a), we substitute the value of a into the function G(x) = x^2 - 5x + 5:

G(a) = a^2 - 5a + 5

Now let's find the equations of the tangent lines to the curve y = x^2 - 5x + 5 at the points (0,5) and (6,11).

To find the slope of the tangent line at a given point, we need to find the derivative of the function G(x), which is denoted as G'(x) or y'.

Taking the derivative of G(x) = x^2 - 5x + 5 with respect to x:

G'(x) = 2x - 5

Now, we can find the slope of the tangent line at each point:

Point (0,5):

To find the slope at x = 0, substitute x = 0 into G'(x):

G'(0) = 2(0) - 5 = -5

So, the slope of the tangent line at (0,5) is -5.

Using the point-slope form of a linear equation, we can write the equation of the tangent line passing through (0,5):

y - 5 = -5(x - 0)

y - 5 = -5x

y = -5x + 5

Therefore, the equation of the tangent line passing through (0,5) is y = -5x + 5.

Point (6,11):

To find the slope at x = 6, substitute x = 6 into G'(x):

G'(6) = 2(6) - 5 = 7

So, the slope of the tangent line at (6,11) is 7.

Using the point-slope form, we can write the equation of the tangent line passing through (6,11):

y - 11 = 7(x - 6)

y - 11 = 7x - 42

y = 7x - 31

Therefore, the equation of the tangent line passing through (6,11) is y = 7x - 31.

Answer:

/ 200 ... i think  

Step-by-step explanation:

10cm = 10 / 100 = 0.1 m

20 / 0.1 = 200

The scale of the diagram is 0.5cm represents 1 meter.

Here, we have,

To determine the scale of the diagram, we can use the ratio of the length of the hall in reality to its representation on the diagram.

The length of the hall in reality is given as 20m.

The length of the hall on the diagram is given as 10cm.

To find the scale, we need to determine how many centimeters on the diagram correspond to one meter in reality.

Let's set up the proportion:

20m / 10cm = 1m / x

Cross-multiplying:

20m * x = 10cm * 1m

Simplifying:

20x = 10cm

Now, we can solve for x, which represents the number of centimeters on the diagram that corresponds to one meter in reality:

x = 10cm / 20

x = 0.5cm

Therefore, the scale of the diagram is 0.5cm represents 1 meter.

The 90% confidence interval for the difference between the proportions of college graduates and individuals with some college who believe in the theory of evolution is (0.022, 0.220)

The sample size of respondents with some college education is 325, and 133 of them believe in the theory of evolution. The sample size of respondents who were college graduates is 228, and 121 of them believe in the theory of evolution.

Now, the sample proportions are:p1= 133/325 = 0.410p2 = 121/228 = 0.531The point estimate of the difference in proportions is:p1 - p2 = 0.531 - 0.410 = 0.121

To calculate the standard error of the sampling distribution of the difference of two proportions, use the following formula:\($$SE = \sqrt{ \frac{p_1(1-p_1)}{n_1} + \frac{p_2(1-p_2)}{n_2}}$$\)

Substituting the values, we get,\($$SE = \sqrt{ \frac{0.410(1-0.410)}{325} + \frac{0.531(1-0.531)}{228}}$$\)

Solving the above expression, we get,\($$SE = 0.0489$$\)

Using the formula of the confidence interval,\($$\text{Confidence Interval} = \text{point estimate} ± \text{margin of error}$$\)

Substituting the values,\($$\text{Confidence Interval} = 0.121 ± 1.645 \times 0.0489$$\)

The equation of the vertical asymptote of the function \(g(x)=4log_{2} (x-2)+5\) is x=2.

Vertical asymptotes are vertical lines that represent the zeros of a rational function's denominator. Asymptotes can also occur in other situations, such as logarithms. It occurs at the x-value that is outside the domain of the function, therefore the graph can never cross it.

There may be a vertical asymptote along the vertical line if a portion of the graph is about to turn vertical. At the point of x along which you discovered the vertical asymptote, the function's value changes to either ∞ or -∞. A vertical asymptote, however, must never touch the graph.

Yes, there exist infinitely many surfaces that contain the given curve,\(`r(t) = t^2 i + ln(t) j + 1 tk`.\)

Given that \(`r(t) = t^2 i + ln(t) j + 1 tk`\).In order to find the surfaces that contain the curve, we can solve for 't' and get three equations, each missing one of the three variables, giving three equations for surfaces that contain the curve.

They are,\(x = t^2 (y = ln(t) and z = 1/t),\)

\(y = ln(t) (x = t^2 and z = 1/t)\)

\(z = 1/t (x = t^2 and y = ln(t)).\)

These three equations represent the surfaces that contain the curve. But, as you mentioned, there are infinitely many surfaces that contain the curve. This is because we can translate the surface infinitely many times and still have the curve lie on the surface.

For example, the surfaces of the form,x = t^2 + a,

y = ln(t) + b and

z = 1/t + c (a, b, c are constants) also contain the curve.

Hence, there exist infinitely many surfaces that contain the given curve, `r(t) = t^2 i + ln(t) j + 1 tk`.

of f(x) at x=a.Now, let us solve the given problem using the definition of the derivative.Part 1: State the definition of the derivativeThe definition of the derivative is given by:f'(x) = lim h → 0 (f(x + h) - f(x))/hwhere f'(x) is the derivative of f(x) and h → 0 denotes that h approaches 0.Part 2: Using the function given, find the numerator and denominator of the limit given in Part 1The function is:f(x) = 15x - 14We need to calculate:f(x + h) - f(x)/h`f(x + h) = 15(x + h) - 14 = 15x + 15h - 14

`Therefore,f(x + h) - f(x) = (15x + 15h - 14) - (15x - 14) = 15hTherefore, the numerator of the limit is 15h and the denominator of the limit is h.Part 3: Using Part 2, find the derivative by calculating the limit as h approaches 0Using Part 2, we have:f'(x) = lim h → 0

The expected value remains at $15, the variance remains at 0, and the standard.

The multipliers for the results remain the same.

Probability Distribution of the Portfolio Bet: There are a total of 9 sample points, and each sample point has a probability of 1/9.

To construct the probability distribution of the portfolio bet, we first need to define the sample points. Since the portfolio is composed of two independent bets on 3 numbers, let's denote the bets as Bet 1 and Bet 2, respectively.

For Bet 1, let's assume the numbers chosen are 1, 2, and 3. The sample points for Bet 1 would be the three individual numbers: {1}, {2}, and {3}.

For Bet 2, let's assume the numbers chosen are 4, 5, and 6. The sample points for Bet 2 would be: {4}, {5}, and {6}.

Now, let's combine the sample points of both bets to create the sample points for the portfolio bet:

Sample points for the portfolio bet: {1, 4}, {1, 5}, {1, 6}, {2, 4}, {2, 5}, {2, 6}, {3, 4}, {3, 5}, {3, 6}.

(a) Probability Distribution of the Portfolio Bet:

To construct the probability distribution, we need to assign probabilities to each of the sample points. Since each bet is independent, we assume that each number has an equal chance of being chosen.

There are a total of 9 sample points, and each sample point has a probability of 1/9.

The probability distribution of the portfolio bet is as follows:

{1, 4}: 1/9

{1, 5}: 1/9

{1, 6}: 1/9

{2, 4}: 1/9

{2, 5}: 1/9

{2, 6}: 1/9

{3, 4}: 1/9

{3, 5}: 1/9

{3, 6}: 1/9

(b) Expected Value, Variance, and Standard Deviation of the Portfolio Bet:

To calculate the expected value (E), variance (Var), and standard deviation (SD) of the portfolio bet, we need to assign a payoff or outcome for each sample point.

Let's assume the payoff for each winning sample point is $15 (which would include the return of the initial $5 bet).

The expected value (E) is calculated as follows:

E = Σ(P * X),

where P is the probability and X is the payoff. Summing up the products of the probabilities and payoffs for all sample points, we get:

E = (1/9 * $15) + (1/9 * $15) + ... + (1/9 * $15) (9 times) = 9/9 * $15 = $15.

The variance (Var) is calculated as:

\(Var = Σ(P * (X - E)^2).\)

For each sample point, we calculate\((X - E)^2\) and multiply it by the probability. Summing up these values, we get:

\(Var = (1/9 * ($15 - $15)^2) + (1/9 * ($15 - $15)^2)\) + ... + (\(1/9 * ($15 - $15)^2\)) (9 times) = 0.

The standard deviation (SD) is the square root of the variance, so in this case, SD = sqrt(0) = 0.

(c) Multipliers when switching from a $10 single bet to the portfolio bet:

When switching from a single $10 bet to the portfolio bet, the multipliers for the results remain the same. The expected value remains at $15, the variance remains at 0, and the standard.
